I've been removing the inlet manifold on my GDI today. I nearly gave up with all those pesky pipe clips, finally got the manifold off. Thanks to all the posts on here, they helped a lot. Put it on some paper down so as to keep it clean (ish). Turned round and wow a puddle of oil out of the manifold on the floor. That yellow line is 1in wide.
No wonder there is quite a lot on the valves.
